I've used Paypal quite a bit and never had a single problem. I've only sent a few things out of the country, but never encountered any problem of any kind.
Once the money hits your Paypal account, then your good to go.....You've just been paid and no check to clear, no banks to visit to make deposits, your done.....go ship.
I don't think their fees are very reasonable, but that's what we pay for the convienence I suppose?
If it's a problem then just ask for a couple dollars more for the product when you advertise it for sale.....jmo.
